This invention is a oontrivanee of apparatus for opening fire-proof shutters from the outside of the building in case of fire and the like. It consists of a spring slide-bolt and hasp for fastening the shutters, contrived so that the hasp will hook on the bolt to fasten, and the bolt may be drawn back by hand to unfasten, the shutters from the inside, and also so that it can be drawn back from the outside of the building by a hand-lever, with which it connects by rods and levers, any desired number of fasteners for asnlany different windows being all connected to one lever, so that they can be opened, and the lever being arranged in a lock-up case, so as not to be exposed to those not authorized to use it.

Figure 1 is an inside elevation of a building, showing the apparatus arranged for three difl'erent windows. Fig. 2 is a section on line w m of Fig. 1, and Fig. 3 is a section on line 31.3 Similar letters of reference indicate corresponding parts.

The bolt has a spring, D, for sliding it forward into the position for receiving the hasp; also a handle, E, by which to slide it back by hand to open the :hutters from the inside, and it is connected by the arm G with the rod H. tobe pulled back from the outside by the lever I, to which the rod is connected by other rods K M and suitable levers or cranks J L. The arm G is so connected to the bolt that the latter is free to slide by hand-lever E without interference by the outside lever contrivance. The rod H may extend along the wholeside of the house and work the bolts of all the shutters in that row,
